OKP-320

OKP-320     Wulfenite and Mimetite     San Francisco Mine, Sonora, Mexico.  Ex. Caroline Les Collection.  This is a fine example of large wulfenite blades (to more than 2 cm each on edge) that compose a specimen measuring 8.1 x 5 x 3.1 cm.  What makes it really interesting is the two generations of orange mimetite balls on the crystals.  The first generation are very small and fully coat each crystal.  The later generation are brighter orange, larger and on show in partial coverage.  The display is very nice and different from the normally material seen from this location.  The piece is in excellent condition, as seen.  The specimen comes with a custom engraved acrylic base, as seen in the images.  $400

 

 

 

 

 

OKP-321

OKP-321     Wulfenite and Mimetite     Silver Bill Mine, Costello Mine Group, Gleason, Cochise County, Arizona.  Ex. Caroline Les Collection.  This is a very fine example of this material.  It shows two generations of tabular wulfenites.  One generation is brown and the second, with the larger crystals, is transparent and yellow.  The mimetite is apple green.  So, obviously, there is lots of color in this piece.  There is also a fair amount of white, transparent to translucent, calcite scattered throughout.  The specimen is quite large for the location measuring 8.5 x 5.5 x 4.7 cm.  It views from all sides and is in excellent condition.  Exceptional specimen.  The specimen comes with a custom engraved acrylic base, as seen in the images.   $1,600

 

 

 

 

 

OKP-322

OKP-322     Wulfenite on Barite    RESERVED    Rowley Mine, Theba, Maricopa County, Arizona.  Ex. Caroline Les Collection.  This domical specimen measures 6 x 5 x 2.8 cm.  It displays bright orange tabular crystals on all sides that stand up in high relief and contrast on bladed barites.  There is no damage and the wulfenites show excellent form and transparency.  This is an atypical Rowley piece and an excellent value.  The specimen comes with a custom engraved acrylic base, as seen in the images.    $350

 

 

 

 

 

OKP-323

OKP-323     Wulfenite   RESERVED   Silver Bill Mine, Costello Mine Group, Gleason, Cochise County, Arizona.  Ex. Caroline Les Collection. This fragile piece is heavily coated with transparent tabular yellow/ orange crystals.  Views great from any direction and appears to be damage free.  The white crystal looks to be a calcite.  The specimen comes with a custom engraved acrylic base, as seen in the images.  7 x 4.5 x 2.7 cm.   $400

 

 

 

 

 

OKP-324

OKP-324     Wulfenite     Erupcion Mine, Los Lomentos, Chihuahua, Mexico.  Ex. Caroline Les Collection.  The Mineralogical Record (vol. 34, no. 6, 2003) article on this region suggests this form may be from the lowest level of the Ahumada Mine.  It appears most were simply tagged as Erupcion, back in the day.         n any case, this fine damage free example has fine tabular crystals to well over a cm each that are transparent.  The piece measures 5.5 x 4.5 x 2.5 cm.  This is certainly a less common variety of crystal from this popular and prolific area.  The specimen comes with a custom engraved acrylic base, as seen in the images.  $450

 

 

 

 

 

OKN-802

OKN-802      Hematite      Florence Mine, Egremont, Cumberland, England.  Ex. Harold Dibble Collection.  This specimen measures 10.5 x 7.5 x 5 cm and is domical in shape.  Well lit the upper surfaces sparkle from micro crystallization.  No damage to this fine, classic example.  $60

 

 

 

 

 

OKN-803

OKN-803     Albite on Orthoclase      Dona Ana County, New Mexico.  Ex. Harold Dibble collection.  Two large orthoclase crystals with overcoatings of flat crystals of albite.  Not a lot of contrast for this material, but the specimen is well formed, damage free, and it sits nicely for display.  $40

 

 

 

 

 

OKN-804

OKN-804      Quartz on Chaladony (variety Youngite)    Guernsey, Hartville District, Wyoming.  Ex. Harold Dibble collection.  From the early 1980s, this piece would have been a fantastic example for the find.  Light purple in color, having a high luster, very three-dimensional, and damage free are all pluses for the piece.  The specimen sits nicely on edge and views from any direction nicely.  The piece has a couple very minor edge contacts as its only connection to surrounding rock.  8 x 7 x 4.5 cm overall.  Far better in hand, especially what I would call the front view (seen in the first and last image).  Very strong yellow green SW UV fluorescence.    $200

 

 

 

 

 

OKN-805

OKN-805    Galena     Madan Rhodopi Muntains, Southeast Bulgaria.  Ex. Harold Dibble collection.  This specimen measures 8.2 x 6 x 5.8 cm and is composed of stepped cubes with some modifications byoctahedral forms.  High luster and no damage.  One area of matrix contact on back is not seen from side, front, and top views.  Minor pyrite, as seen.  $40

 

 

 

 

 

OKN-807

OKN-807      Geode     Brazil.  Ex. Harold Dibble collection.  This polished hemisphere measures 9 x 7.2 x 5.2 cm.  It has the traditional quartz druse lining its interior as well as some larger more prismatic clear quartz crystals.  No damage.   $20

 

 

 

 

 

OKN-808

OKN-808    Galena, Chalcopyrite, Sphalerite     Madan Rhodopi Muntains, Southeast Bulgaria.  Ex. Harold Dibble collection.  This specimen measures 11 x 6.5 x 5 cm overall and is dominated by stacks of the three species mentioned and overgrown in places by dirty looking quartz crystals (white).  No damage, less a tiny chip on the largest chalcopyrite crystal, as seen.  $45

 

 

 

 

 

OKN-809

OKN-809     Galena     Naica, Chihuahua, Mexico.  Ex. Harold Dibble collection.  This fine plate of interlocking crystals measures 8.7 x 5.1 x 3 cm.  It has a very high luster and no damage.  There is some edge contacting but the edges are generally in good condition.  Minor pyrite and quartz on edges and base.  Mounted on acrylic base.  $40

 

 

 

 

 

OKN-810

OKN-810     Agate Geode   Brazil.  Ex. Harold Dibble collection.  A polished half measuring 10 x 8.7 x 3.7 cm overall.  Bright yellow green fluorescence.  No damage.  $15

 

 

 

 

 

OKN-811

TRUE color

OKN-811   Fluorite     Cave-In-Rock, Illinois.  Ex. Harold Dibble collection.   This is a large partial cube that measures 9.5 x 7.5 x 6 cm which would not show true color when I photographed it.  I've left these off color photos so it can be evaluated for shape and condition.   HOWEVER, it is BLUE with a minor purple core.  It has big, gemmy blue sections and a thin purple phantom.  The last photo was taken with my cell phone and does show how it looks in hand to the eye in any light.  There is chipping as can be seen but it is still a desirable example in a very desirable color.  $150

 

 

 

 

 

OKN-812

OKN-812      Geode     Brazil.  Ex. Harold Dibble collection.  This polished hemisphere measures 8.5 x 7 x 4.2 cm.  It has the traditional quartz druse lining its interior as well as some larger more prismatic clear quartz crystals.  No damage.   $20

 

 

 

 

 

OKN-813

OKN-813     Quartz (Variety Laguna Agate)      Ojo Laguna, Chihuahua, Mexico.  Ex Harold Dibble collection.  This hand size Laguna measures 11.3 x 7.5 x 6 cm and is an exceptional example of this form of quartz.  It is not cracked, as is common with these, the color, especially the desired red, is vibrant and consistent throughout the piece, and it is beautifully polished.  No damage.  There is lots of junky material available that is marketed as Laguna Agate but you will need to do some serious searching to find one of this quality for sale.  When these are this nice they are highly desired by collectors.  $950

 

 

 

 

 

OKO-937

OKO-937        Diopside on Albite      Rose Road Wollastonite Occurrence, Pitcairn, St. Lawrence, County, New York.  Collected by Michael Walter, summer 2006.  This is a 9.5 x 6.6 x .5 cm plate of crystals with crude albite but, excellent diopsides to 2.5 cm each.  They are deep green, which is typical of the good ones, and well formed, which is unusually for any from this location.  They have glassy lusters and are quite aesthetic.  No damage.  This one could be trimmed further in that all the best crystals are on one end of the piece, as seen.  $110

 

 

 

 

 

 

OKO-937

Back?

OKO-938     Pyrite      Route #81, Syracuse, Onondaga County, New York. Ex. Chuck Bowman collection.  A uncommonly large example from this once prolific site that measures 9.4 x 4.5 x 3.7 cm with cubes to over 3 cm each on edge.  It is as large as the largest and finest figured in the Rocks and Minerals Magazine article (March/April 1983, vol. 58, no. 2).  The front is clean without damage but, the back shows some chipping.  The piece is a floater cluster with the typical matt luster associated with this material.  Very nice and uncommon to find in today's market.  $300

 

 

 

 

 

OKO-939

OKO-939     Magnetite and Other species     2,500 foot Level of the Zinc Corporation of America Mine, Balmat, St. Lawrence, County, New York.  Ex. Chuck Bowman, Z.C.A. miner and collector of specimen.  Rare, well documented, and important material that is unique to the mineralogical world.  It also ranks among the best known for the species.  This example is composed of very high luster, simple cubes with talc/anhydrite/sphalerite mixes filling in between many crystals on the front and less so on the back.  Of course, that depends on which side you will call the "front" because both are excellent.  8.8 x 7.4 x 4.4 cm.  Very minor chipping to a couple cubes on edges only so the piece is in excellent condition, sits well, and displays great.  $250

 

 

 

 

 

OKO-941

OKO-941     Magnetite and Sphalerite     2,500 foot Level of the Zinc Corporation of America Mine, Balmat, St. Lawrence, County, New York.  Ex. Chuck Bowman, Z.C.A. miner and collector of specimen.  Rare, well documented, and important material that is unique to the mineralogical world.  It also ranks among the best known for the species.  This 8 x 6.8 x 4 cm piece is dominated by a high luster crystal on its top that is partially exposed from within massive anhydrite and calcite.  The main crystal is 1.7 cm on edge and composed of the most desirable forms (cube, tetrahexahedron, and minor octahedral modifications on corners).  The cube is damage free.  On its backside is another attached cube that has strong healed contacts.  So, the back view is less aesthetic.  There are other damage free cubes only partially exposed on the front and back but further work is needed to expose them.  This is an excellent example and a value for the quality of this modern classic.  $375
